The Muertes Archipelago, also known as The Five Deaths (Las Cinco Muertes in Spanish), is a chain of five islands 200 miles southwest of Costa Rica. They are named Isla Matanceros, Isla Muerta, Isla Pena, Isla Sorna and Isla Tacaño. The name comes from a Native American myth about a brave warrior facing a different execution on each of the five islands: burning, drowning, crushing, hanging and beheading. The islands were revealed in the sequel to the Jurassic Park film and novel.
It is commonly believed that InGen owned all of the Five Deaths although there is no evidence that they did. There is only evidence that they owned Isla Sorna, which was likely the only island populated with dinosaurs aside from Isla Nublar at any point in the franchise.
The five islands were part of a group of at least twenty islands. They had temples with colorful illustrations of the executions that took place on each island in the myth. This artwork was documented by German scientists in the book Die Fünf Todesarten.
The shapes and positions of the five islands are not shown in the book, only a map of Isla Sorna is shown. Ian Malcolm says that the islands form a bow. They lie 15 kilometers from the mainland.
The video game The Lost World: Jurassic Park shows a map of the Five Deaths. Since the shape of Isla Sorna matches the version from novel, these maps might reflect the Five Deaths from the Novel canon; however, the islands lie in an X-shaped configuration, rather than the bow shape from the novel. The islands from top to bottom are: Isla Sorna, Isla Matanceros, Isla Tacaño, Isla Pena and Isla Muerta.
The shapes and positions of the islands are only seen when Kelly Curtis Malcolm sneaks into the trailer and sees a map on the wall. Another map of the Five Deaths appears in the Jurassic Park III Prop Set. This time the islands form a bow, as stated in the novel. The islands from left to right are: Isla Matanceros, Isla Muerta, Isla Sorna, Isla Tacaño and Isla Pena. Isla Nublar is placed halfway between the Five Deaths and the mainland.
The bow-shaped configuration from the The Lost World: Jurassic Park is reprized for Frontier Developments' business sim. In this game, InGen owns all five islands, with all islands being locations for development and research.
In a later book by Crichton, Pirate Latitudes, there is an island in the Caribbean named Matanceros. This may be a reference to Isla Matanceros.
